Title: Numerical display distortionmeter
IPC: H04L25/04
Filed: 1971-10-28
Abstract: 1307508 Telegraphy distortion measurement COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 28 Oct 1971 [28 Oct 1970] 50127/71 Heading H4P A telegraph distortion meter providing a numerical display, has a first clock pulse counter for reset in response to transitions in a distorted signal when the count exceeds half its capacity, and a second counter similarly reset to transitions occurring when the count is less than half its capacity.  Clock pulses H1 equal to 1/1000 of the signal interval are received by a first modulo counter comprising a 1/500 divider 11 forming a modulo 500 counter in series with a ¸2 divider in the form of a triggered flip-flop 13 so that when the count is 0-499 output K1=0 and 500-999 K1 = 1, K1 being the complement. Clock pulses H1 are also applied to an identical arrangement 12, 14 giving similar outputs K2 and the complement K2. Receive signals are applied at E for an interference suppresser P to terminal 10 connected to the C input of a JK flip-flop 15, the J input of which is held at 1 and K input at 0. The reset input R receiving a signal defining an instant T0 signifying the beginning measurement cycle which signal may be provided manually or otherwise.  When Q output of a flip-flop 15 is at 0 a gate 70 is open and the first transition of the receive signal passes through gates 19, 20 which reset counters 11, 12. The second transition is blocked by gate 16 but passes through gate 18 to reset counter 12 to zero; the third transition is blocked by gates 16, 18 and the fourth passes through gate 16 and resets counter 11 to zero and similarly the fifth transition. Interference suppressor P operates on the principle that if a change in amplitude lasts less than a predetermined interval then it is spurious i.e. if a change in amplitude does not last a predetermined interval d i.e. the counter (30), Fig. 3 (not shown), does not achieve a count of 16 then it is assumed that this is an interference pulse and only after this count, the state of a flip-flop (46) changed is for an appropriate time. The arrangement may accommodate amplitude transitions of either polarity. The counter 11 is only reset when a signal transition occurs during a count of 500-999 and records delays, and counter 12 is only reset during a count of 0-499 indicating an advance. At the beginning of each measurement cycle both counters are reset to zero and the difference between counts any time is proportional to the arithmetic sum of the greatest delay and greatest advance. The difference in counts may be measured by counting the number of pulses between the reset operations in counter 25 which controls display element 26: the indication being given as a percentage.

Abstract: 1,111,869. Preheating open hearth furnace charges. THRINGS EXPERIMENTAL DEVELOPMENTS Ltd. 2 Dec., 1966 [4 Dec., 1965], No. 51540/65. Heading F4B. A continuous steel-making furnace of the multiple open hearth type comprises a pre-heating floor 11, a narrowing melting hearth 9A, 9B, 9C, and an elongate refining hearth 1, scrap material being charged by reciprocating rams 13, successive charges pushing others across the pre-heating floor to the melting floor down which the scrap falls by gravity. Burners 15 melt the scrap which flows into the refining hearth 1 where slag-forming material is introduced by a water-cooled screw conveyer (7, Fig. 1) and a second burner (2, Fig. 1) acts on the molten iron. The refined steel is withdrawn by vacuum de-gassing apparatus (21) at the end of the refining hearth remote from the charging end. Combustion gases from the burners pre-heat the scrap on the preheating floor, and are released through duets which may be in the roof of the furnace as shown, or in the side walls (Fig. 5), or in the floor 11, covered by water-cooled gratings (18, Fig. 1), and are used to pre-heat combustion air for the burners, or to pro-reduce iron ore.

Filed: 1967-11-16
Abstract: 1,202,288. Increasing buoyancy of amphibians. BOFORS A.B. 16 Nov., 1967 [21 Nov., 1966], No. 52302/67. Heading B7S. [Also in Division D1] A bellows structure of water proof impregnated fabric of heat fixable material is made by placing the fabric in intended folds, maintaining the fabric under pressure in this position and subjecting the fabric to heat treatment at a sufficient temperature and for a sufficient period of time to permanently fix the fabric. The structure is intended to be attached to the upper surface of a vehicle, e.g. a tank or armoured car, and can be drawn up to extend above the vehicle to allow it to float in water. The fabric is made of nylon, polyethylene terephthalate or polyacrylonitrile and is made water proof by impregnation with natural or synthetic rubber. The fabric is sewn to the required shape of the structure, i.e. rectangular with chamfered corners, and the intended fold lines are drawn thereon. The structure is suspended from a frame-like carrier 1, Fig. 3, to hang loosely over a template 2 which comprises a frame 3, Fig. 9, having inner and outer posts 4, 5 which project upwards to a height greater than the height of the collapsed bellows structure. The bottom edge of the fabric is secured by temporary clamps 6, Figs. 3 and 4, which engage around the frame 3. Each clamp 6, Fig. 4, comprises a rod 11, a stationary plate 12 and a movable plate 13 provided with a resilient stirrup 14 through which the rod 11 passes. If desired, the outer folds are prefixed by securing clamps 1 thereto and then applying heated tongs (7a), Fig. 1 (not shown), at a temperature of 100‹ C., for example. The structure is positioned in the template in the form shown in Fig. 9 with the prefixed outer folds against the posts 5 with members 8, slidable on the posts 5, positioned between adjacent folds. On the opposite side, members 9 rest against the posts 4 and are provided with plates 10 which extend internally of the prefixed folds. Displacement of the fabric is prevented by positioning U- shaped clamps 15 around the folds. When the complete structure has been folded in the template, cover plates 16 are placed thereover. Clamps (17), Fig. 5 (not shown), are applied to compress the fabric between the plates 16 and the frame 3. Each clamp (17) comprises belts 18, 19, Fig. 9, and cross-pieces 20, 21. The clamps 6, 15 are removed and the template 2 is introduced into an oven, e.g. at 100-200‹ C. for ¢-2 hours, to permanently fix the folds of the bellows structure.
